Sphinx: IGT's Egyptian Pick-Bonus Classic

Sphinx by IGT is a 5-reel, 3-row Egyptian slot that made its name on casino floors before moving online. Rather than chasing modern gimmicks, it leans on a tight base game and a layered pick-style bonus built around the silent guardian of the pyramids. The golden tones, hieroglyphic detailing and the sphinx itself give it a polished, unmistakably IGT look.

If you have played IGT machines in a physical venue, the familiarity is immediate. The digital version keeps that land-based feel while running cleanly in the browser, making it an easy game to pick up and an easy one to try as a free demo.

Reels, Paylines and Symbols

The game uses a fixed 5x3 grid with 9 paylines. Wins form when matching symbols land left to right across one of those lines. The symbol set stays true to the theme: pharaohs, scarabs, ankhs and other ancient artifacts sit above the usual playing-card values that round out the lower-paying positions.

The golden Tutankhamen mask is the wild. It substitutes for every regular symbol except the bonus coin and is also the top-paying symbol on its own, rewarding longer matching runs across the reels. A fully wild screen is what produces the game's headline payout, covered below.

The Bonus Coin Scatter

The bonus coin acts as the scatter. It pays from any position rather than needing to land on a specific line, and landing three or more anywhere in view is what opens the Sphinx Bonus. The scarab also contributes scatter-style pays, rewarding several on screen regardless of where they fall. Because the coin pays from anywhere, it is the symbol you are watching for on every spin.

Sphinx Chamber Pick Bonus

This is where Sphinx stands apart from the free-spins formula. There are no free spins here. Instead, three or more bonus coins trigger a two-stage pick feature. In the first stage you open sarcophagi to reveal instant prizes or arrows that advance you deeper into the round.

Reach the second stage and you face the Sphinx Chamber, choosing among stone statues that hold multiplier prizes. The values climb steeply, up to 2,500x your bet at the top end, so the bonus is the clear driver of the game's bigger results. The base game delivers steadier, smaller hits, while the pick round is where the session can swing.

Maximum Win and Volatility

The top payout is 10,000x your stake, achieved when the reels fill entirely with golden mask wilds. That is a rare line-up, but it sets the ceiling for the base game on top of whatever the pick bonus pays. Sphinx runs at medium volatility, so wins arrive at a reasonable pace without the long dry spells of a high-variance title. The RTP varies by operator configuration, as IGT releases this game in more than one return setting, so check the in-game paytable for the version you are playing.

Playing Sphinx Free on Mobile

Sphinx is built in HTML5 and runs natively in a mobile browser, so there is no app or download involved. The reels and controls scale to fit the screen, touch input handles spinning, bet adjustment and the paytable, and the pick bonus behaves exactly as it does on desktop. Landscape orientation gives the widest view of the grid, though portrait works fine for quick sessions.

The demo above loads instantly with no sign-up. You are playing with virtual credits, which makes it a low-stakes way to learn the symbol pays and see how the two-stage bonus unfolds before deciding whether the game suits you.
